Fourier-Mukai partners of abelian varieties and K3 surfaces in positive and mixed characteristics
Riku Kurama
We study Fourier-Mukai equivalences of (families of) abelian varieties and K3 surfaces in positive and mixed characteristics. We first prove in any characteristics that Fourier-Muk…

Weyl-invariant subspaces are (usually) not generic
Riku Kurama, Ruoxi Li, Henry Talbott +1
Let be a linear representation of a connected complex reductive group . Given a choice of character of , Geometric Invariant Theory defines a locus $V^{ss}_θ(G) \su…

Countability of relative Fourier-Mukai partners
Riku Kurama
Anel and Toën proved that a smooth projective complex variety has only countably many smooth projective Fourier-Mukai partners up to isomorphism. This is generalized in the Stacks…
